How to set similiar lighting
My advices:


Your scene and that scene has different type of hdris.
Install hdri addon like gaffer (it's free) and change/rotate different hdris until you find what looks most similar.
If you want the most similar look you wil have to use exact same hdri image, if it's possible but in most cases it isn't possible.
That scene has hdri of clear noon sky and you have hdri of evening or something like that.
So both images represent different time span of the day. 
You image looks darker so after you change the hdri, you should increase the strength of hdri before tweaking the sun lamp
The image you are using is already post processed image


So you will have to concentrate on post processing as well as lighting of your scene


Blender has good composition system but i would recommend adobe lightroom for this. I use it's free android app to do the post processing. 
He has used some soft area lamps
